- Imagine you are standing at a microphonein front of a crowd.Checking your notes,you begin speaking.Using the information in this chapter,describe the series ofevents in particularregions of the brainthat enabled you to saythe very first word.In 2003, the Nobel Prize in Physiology or Medicine wasawarded to Paul C. Lauterbur and Sir Peter Mansfield fordiscoveries related to magnetic resonance imaging (MRI).This is a tool to see the structures of the body (not just thenervous system) that depends on magnetic fields associatedwith certain atomic nuclei. The utility of this technique inthe nervous system is that fat tissue and water appear asdifferent shades between black and white. Because whitematter is fatty (from myelin) and gray matter is not, theycan be easily distinguished in MRI images. Visit the NobelPrize website (http://openstaxcollege.org/l/nobel_2) toplay an interactive game that demonstrates the use of thistechnology and compares it with other types of imagingtechnologies. Also, the results from an MRI session arecompared with images obtained from x-ray or computedtomography. How do the imaging techniques shown in thisgame indicate the separation of white and gray mattercompared with the freshly dissected tissue…Pain/temperature information from the body crosses over to the other side of the body (decussates) in wh. structure? the spinal cord O the medial lemniscus of the medulla the corpus callosum the anterior commissure
- What part of the nervous system produces the currents and voltages visualized with an EEG ? Individual cortical neurons Axons of many thalamic neurons Dendrites of many pyramidal neurons15) Examine the diagram of a reflex arc shown below. In this case, pain from tissue damage to the hand results in a response where muscles move the hand away from the painful stimulus. ST. gridld.doi vd ehow or2 1o notelvib dot Figure 38-10 Biology; Life on Earth, 8/e © 2008 Pearson Prentice Hall, Inc. barostin 20 a) On the diagram above, label the motor neuron, the sensory neuron, the interneuron, and the effector. b) List any way or ways in which the nervous system will determine the intensity of the pain the example above. Corobral cortexWatch this video (http://openstaxcollege.org/l/whitematter) to learn about the white matter in the cerebrum that develops during childhood and adolescence. This is a composite of MRI images taken of the brains of people from 5 years of age through 20 years of age, demonstrating how the cerebrum changes. As the color changes to blue, the ratio of gray matter to white matter changes. The caption for the video describes it as less gray matter, which is another way of saying more white matter. If the brain does not finish developing until approximately 20 years of age, can teenagers be held responsible for behaving badly?
- Watch the video (http://openstaxcollege.org/l/2brains) titled The Man With Two Brains to see the neuroscientist Michael Gazzaniga introduce a patient he has worked with for years who has had his corpus callosum cut, separating his two cerebral hemispheres. A few tests are run to demonstrate how this manifests in tests of cerebral function. Unlike normal people, this patient can perform two independent tasks at the same time because the lines of communication between the right and left sides of his brain have been removed. Whereas a person with an intact corpus callosum cannot overcome the dominance of one hemisphere over the other, this patient can. If the left cerebral hemisphere is dominant in the majority of people, why would right-handedness be most common?Watch this animation (http://openstaxcollege.org/l/braindevel) to examine the development of the brain, starting with the neural tube. As the anterior end of the neural tube develops, it enlarges into the primary vesicles that establish the forebrain, midbrain, and hindbrain. Those structures continue to develop throughout the rest of embryonic development and into adolescence. They are the basis of the structure of the fully developed adult brain. How would you describe the difference in the relative sizes of the three regions of the brain when comparing the early (25th embryonic day) brain and the adult brain?Watch this video (http://openstaxcollege.org/l/3Dmovies) to learn about the side effects of 3-D movies. As discussed in this video, movies that are shot in 3-D can cause motion sickness, which elicits the autonomic symptoms of nausea and sweating. The disconnection between the perceived motion on the screen and the lack of any change in equilibrium stimulates these symptoms. Why do you think sitting close to the screen or right in the middle of the theater makes motion sickness during a 3-D movie worse?
- Read this article (http://openstaxcollege.org/l/3word) to learn about a young man who texts his fiancée in a panic as he finds that he is having trouble remembering things. At the hospital, a neurologist administers the mental status exam, which is mostly normal except for the three-word recall test. The young man could not recall them even 30 seconds after hearing them and repeating them back to the doctor. An undiscovered mass in the mediastinum region was found to be Hodgkins lymphoma, a type of cancer that affects the immune system and likely caused antibodies to attack the nervous system. The patient eventually regained his ability to remember, though the events in the hospital were always elusive. Considering that the effects on memory were temporary, but resulted in the loss of the specific events of the hospital stay, what regions of the brain were likely to have been affected by the antibodies and what type of memory does that represent?Watch this video (http://openstaxcollege.org/l/basalnuclei1) to learn about the basal nuclei (also known as the basal ganglia), which have two pathways that process information within the cerebrum. As shown in this video, the direct pathway is the shorter pathway through the system that results in increased activity in the cerebral cortex and increased motor activity. The direct pathway is described as resulting in disinhibition of the thalamus. What does disinhibition mean? What are the two neurons doing individually to cause this?Watch this video (http://openstaxcollege.org/l/lumbarpuncture) that describes the procedure known as the lumbar puncture, a medical procedure used to sample the CSF. Because of the anatomy of the CNS, it is a relative safe location to insert a needle. Why is the lumbar puncture performed in the lower lumbar area of the vertebral column?
